Cannot access a closed Stream. - Multi page snippits

[stephenhendry]

I have found a bug with multipage documents that contain snippets. Once you go over one page you then get the error:

Cannot access a closed Stream.

To reproduce this change GetModel() in PdfController.cs to

        private DemonstrationModel GetModel()
        {
            return new DemonstrationModel
            {
                People = new List<string> { "Alice", "Bob", "Charlie", "Alice", "Bob", "Charlie", "Alice", "Bob", "Charlie", "Alice", "Bob", "Charlie", "Alice", "Bob", "Charlie", "Alice", "Bob", "Charlie", "Alice", "Bob", "Charlie", "Alice", "Bob", "Charlie", "Alice", "Bob", "Charlie", "Alice", "Bob", "Charlie", "Alice", "Bob", "Charlie", "Alice", "Bob", "Charlie", "Alice", "Bob", "Charlie", "Alice", "Bob", "Charlie", }
            };
        }

Then go to /Pdf/ControllerlessPdfWithLayout.

Had a quick look and the line that is causing the issue is in AggregateHelper.cs

var snippetData = _pdfGeneratorFunc(null, snippet.Model, snippet.View, null, snippet.Margins);

This is pointing to InternalGeneratePdf.
